Rendering primitive parent class. These objects are usually created by a 'Primitive' subclass when rendering is done. The primary difference between two classes is that the 'Primitive' always remains in scene space, or world space, and a rPrimitive is allocated per render sample and transformed into clip and screen space. These objects are destroyed after rendering is complete.
